Well, I seem to hold an unpopular position here.
I will just make a few more points and then shut-up
Of course I perform check lists when I am the pilot. It is part of my professional duty to do so. I would say I am more particular about this than many of the FO’s with whom I fly. I find in general there is a tendency to recitation rather than really checking – for what it’s worth.
However, when I am a passenger, this is a different matter. Now I am a member of the public. I take responsibility for my own safety, and I base my actions on my assessment of risk. I know where the exits are without the briefing, because I look, And, lets face it, most passenger cabins are pretty standard.
To all those who seem to worry about air crashes, I would ask:
Do you wear a crash helmet while driving?
Why not. It is easy and pretty cheap and it will save your life more often than an obsessive interest in safety briefings.
